mnemonic security podcast

Hosted by Robby Peralta from mnemonic, one of Europe’s leading cybersecurity companies, the show features conversations with researchers, founders, operators, and security leaders working across the cybersecurity landscape.

Each episode explores a specific topic within cybersecurity: from incident response, threat intelligence, AI, and geopolitics, to leadership, resilience, and the changing role of security leaders.

The podcast is tailored to cybersecurity practitioners and decision-makers who want grounded conversations about where cybersecurity is going, what organisations should prepare for, and what experienced people are seeing.
